GLENN J. BARRETT, OF GRAND RAPIDS, MICHIGAN, ASSlGNOR TO BARRETT ADDING MACHINE COMPANY, OF PHILADELPHIA, PENNSYLVANIA. A CORPORATION OF DELAWARE.

Application filed February 4. 1918.

T 0 all whom it may concern Be it known that I, Gmzxx J. BARRETT, a citizen oi thc United States, residing at Grand Rapids, Michigan, have invented certain new and useful lmprovements in vice of .such' character which will 'automati-i cally lock 'the keysot such columns of an adding nacliine' -as may be desired against depressionzftq', render-the same inoperable;

to provide a device'of such character that it win admit and will enahl'e"the division of the" keyboard in such manner as may meet the operators' convenience and requirement-spandalso to provide a device of the character which may be i eadi'ly removed from position unogithe machine when not in use.

Other and further ohe ts of my invention will he hereinafter-'1 referred to in the specification or \y ill beapparent therefrom.

In the accompanying "drawings *1 have, illustrated a 'striiof 'n'e' show'in'g a convenieiit embodiment ofjinyfinvention and also illustratingtlieFprinciple' of operation of the same- HoWcv-erg'ljt should be under- 35 stood thatch'ang in the details of, const ruct-ion may; he; made}. within the scope of the claims withhnt departing from my invention,

In -otdei' that my invention may bonfire {3'0 readily clearly comprehended, refer encezshou'ld" be had to the accompanying e diga vyings, in wh1ch,-= i

'2. the said section extending only through the top plate of the casing of the adding machine: Fig. i is a longitudinal sectional view taken on the line of Fig. 2, the said section extending only through the top plate of the adding machine ,and thesaid view. also showing a divider emoodving my invention in edge elevation, and some of the key stems of one of the columns of keys: and Fig 5 is a perspective view of one of the devices embodying my invention.

I ha e illustrated my invention in connection with a form of adding machine illustrated in United States Letters Patent No. 976,336. issued Xovemher 22nd, 1910, but 'it will be understood that the form of adding machine to which my invention is applied immaterial.

In the drawings,-l designates the easing of an adding. machine and. 2 designates an operating handle of known construction.

The said machine is provided as usual with a number oi columns of key stems which extend longitudinally-10f themachine. The

, de ice whichv constitutes a denominating divider consists of a main or body portion -.3 having carts-4e and 5 which project laterall v from its upper or rear end portion.

The purpose of these ears is to prevent the Patented Feb. 9, 1915.

other sign designated by the reference nu-' ineral 8'is placed upon the device to corre spond with any special denomination of money, as, for instance, one dollar bills, two dollar billsefive dollar bills, etc., or five cents',* -ten cents, twenty cents, etc. The

lower end of each device designated by the reference numeral 10 constitutes an indicatorjfor indicating the. dial of units denomi- I nationiin the column cotipera'ting with the stems opposite,- the numeral or other symbol designated by the; reference numher 8.

11 designates a pointer alining with the co-lu'mnof key stems'in which additions are to bev madewhen using my device. It will be observ ed upon reference to the drawings, particularly Figs. 3 and 4, that the locking cars or projections 6 when the device is in operative position are situated directly underneath the heads 12 of the key stems so as to prevent operation of such key stems as may have their heads so situated with respect to such ears or projections.

a The use of devices I bodying my inventionlmay be readily understood by reference to Figs. 1 and 2 of the drawings. I=

shall first describe the operation of the same in connection with F ig.-1in "which devices are arranged'for determining the denominations and number of each required for bills or amounts to the left of the decimal point. It will be seen that two .columns are allowed at the extreme right hand, of the key-board for the one dollar bills; that three columns are allowed for the five dollar bills; that three columns are allowed. for the ten .dollar bills, and'tha-t two col- Y umns are allowed for bills of the denominaeach of various denominations of currency necessary to 'amounts,

make up the following $12243 I Considering first the amounts oj?the1items to the'left' oftlie decimal p'oifits'dn order,

we find that to makeup the sum of thirty six dollars, one-twenty, one ten, ione five, and one one.dolla r' bill are requiredi Ac-- vc ordingly in each column covering the above denominations which are opposl'teth'e nu- 'merals 20, 10, 51and 1, ,a-key stem-having a button or head'with the numeral 1 thereon, is depressed becausegtherezg's but-one each jof the various denominations making .up

the sum of $36.00 required. The-machine :shown in the drawings being a key set'handle operated adding Imachme, the handle 'is drawn forward .after the sversilkeys have been set andthe dials 131.5113 with the respective columns recor or indicate the number ofeach denominatiomwhichds required. The;nert-'item, twenty-five dollar's',- will require onestwenty'and one five dollar bill. Accordingly, "a 91",. button ri 1 f depressed in the columns corresponding to 2 those denominations on the denomination dividers and the handle-operated as before. The item twenty-four dollars is made up of one twenty dollar bill and four ones, and requires the depression of a 1 button 'in' the column opposite, or in alinement with, the numeral 20, and a 4 button in the column opposite, or in alinement with, the numeral 1 onthe device at-the right hand side of Fig.1. The item sof twelve dollars comprising a ten 'dqlla'r'bilI and two one dollar bills, requiresfthe" depression of button in the 1 column. Thei ten' 1-of5;nine dollars comprising a five dollarf'bi four ones, requires the depressiofiigofj button in the 5 column and 3. 251: in the 1 column. The item of (Si ones, requires the depression of a 1? but; ton in the 5 column and .a 3 button in the 1 column. The item "of four dollars which is the last one given in the problem to be solved, requires the depression "of. a 4 button in the 1 column."

ginning the -number of each upoh' theother-or left-=h sideofto-make up these several u hthand-sidg of the decimal points, four -ce'nt pieces, sir; 'quarters egght' dimes, one nickel and thirteen one cent pieces will "be required. These'amounts be seen upon the respective dials in Fig. 2 of the drawings The operator may then check up" these amounts by takin firstthe denomi-, nations to theleft of the ecimal points and adding the values they-represent, for in-" stance, three twenty-dollar'bills, two tens,

four fives, andei hteen ones, which make a total .ofone hun redandeighteen dollars. In the same way b. adding what is represented the "dials nFig. 2 he find the loo orator should clear the adding;

' the decimal points. L'ftei=fhavmgharried; ,this operation through it Wil1"bg -found that pan the total to be $L48. Then by adding these sums together he will secure a total of one hundred twenty-two dollars and forty-eight cents.
